Design of Weight: How do we feel force, and how can we apply it to product design?

November 29, 2016 at Kashiwanoha Conference Center, Kashiwanoha, Japan
Workshop on AsiaHaptics 2016


Objectives: This workshop will discuss how we feel force, and try to design comfortable weight. It is composed of lectures, and a hands-on experience program of making various products. Through this workshop, we expect that the participants will be interested in what comfortable weight is, understand the applicability and potentiality of comfortable weight, and have an idea for basic researches of comfort perception and applications into industrial products.

Significance and Impact: Our workshop gives broader impacts for participants. As stated above, understanding the weight feeling is important not only for raising proper questions in haptics research but also for applying this knowledge into consumer product design in manufacturing. We handle both of these topics at the same time and provide participants with comprehensive understanding of weight feeling. Proposed workshop is the best opportunity for learning the outcome of basic research on the weight perception in short time.



Introduction: motivation and objectivities of this workshop

Yuichi Kurita, Hiroshima University


Lecture: Texture design

Yoshihiro Tanaka, Nagoya Institute of Technology


Lecture: Haptic display by skin deformation (tentative)

Masashi Konyo, Tohoku University


Making interesting feeling of weigt by changing the surface texture, color, shape, and size of an object. We will provide various materials. Participants will enjoy creating their own products and evaluate textures each other.
(1)How to make (by organizers)
(2)Making own product (by each participant)
(3)Presentation of resultant product (by each participant)
(4)Vote for comfortable texture

* The numbers of provided materials are limited. If participants are too many, we will make groups.


The workshop will be of general interest to industrial or academic researchers on haptic/tactile design, haptic/tactile devices, and haptic/tactile perception, and artist and educators who are not familiar with haptics but who wish to establish haptic/tactile design and possible applications. Students who will start haptic researches are also welcomed audience.

Yoshihiro Tanaka, Nagoya Institute of Technology / JST, PRESTO
Tanaka received the Ph.D. in engineering from the Graduate School of Engineering, Tohoku University, in 2006. In the same year he worked as a research associate in Nagoya Institute of Technology. Currently, he is working as an associate professor in the Graduate School of Engineering, the same university since 2009. He worked as a visiting researcher at Utrecht University in 2011. From 2014, he was a PRESTO researcher in the foundation of design of information infrastructure technologies harmonized with societies in Japan Science & Technology Agency. His research topics are quantitative evaluation of tactile feelings and tactile product design. He has often studied haptics under collaboration with manufacturing companies. Recently, he discussed the bidirectional relationship between touch behavior and tactile feelings.
